Siemens Announces 10 Gbps PON Breakthrough, 100km Range

Researchers from Siemens Networks demonstrated the ability to transmit data at 10 Gbps error-free over a passive optical access network -- this is four times faster than current GPON technology. The upstream capacity was rated at 2.5 Gbps and the number of subscriber lines per splitter was expanded to 512. Siemens also achieved a 100 kilometer distance between hub and subscribers -- the so-called last mile. Current PONs typically support subscribers within a 20 km radius.



The higher split factor in urban areas allows considerably more subscribers to be connected to a system. It also eliminates the need for the aggregation devices that are now commonly used to collect and distribute data traffic locally. Siemens predicts that in the future, it will be possible to connect subscribers directly to the core network.



In its research for the new PON system, Siemens implemented an optical amplifier, a so-called erbium-doped fiber amplifier (EDFA). Only through use of an EDFA can the extended reach and greater subscriber number be achieved. Optical fibers doped with the element erbium amplify the optical signal of the system and enable longer transmission ranges with higher bandwidth. This device was developed by Siemens in such a way that a purely optical bi-directional amplification is possible. The result: One single compact device can boost optical signals both from the end customer to the exchange and from the exchange to the subscriber.



"We are very confident that we can further develop systems of the next PON generation to reach final market readiness by the year 2009," said Christian Unterberger, President Fixed Networks at Siemens Networks.



In addition to Siemens, the universities of Eindhoven and Essex, the Heinrich-Hertz-Institut Berlin of the Fraunhofer Gesellschaft and leading European network carriers are participating in the Extended Reach PON Systems project.

Avici's Soapstone Develops Abstraction Layer Above MPLS, PBT

Avici Systems has formed a new business unit, called Soapstone Networks , that will offer a network control layer solution that sits between IT-hosted services and network/transport. Soapstone will leverage key industry standards such as ITU NGN, SOA, TMF eTOM, and others, along with open application programming interfaces (APIs) between the network and IT/OSS systems. The Soapstone aim is to map the abstract service needs expressed by the business plane into a simple configuration command set that can be applied to any technology or equipment.



Phase One of the Soapstone product rollout will include the availability of a Provider Backbone Transport Controller (PBTC). Instead of MPLS, PBT uses low-cost Ethernet switching and can link the OSS and network with a simple API. In order for PBT to support automated provisioning and fault management and ultimately control operations costs, it requires a reliable and scalable control plane. Soapstone PBTC is a virtual control plane for PBT, but also one that is compatible with other network technologies such as IP.



Soapstone will deliver a transport abstraction layer above both PBT and MPLS, enabling the migration from already-deployed MPLS networks to PBT.



Soapstone also aims to deliver key capabilities for IMS applications by decoupling IMS from the network, a function IMS recognizes in its definition of a Resource-and-Admission Control Function (RACF). The company plans to support the full ITU NGN RACF capability set, making it compatible not only with IMS but also with emerging FMC applications and even session-based wireline applications including voice and video over IP.



Soapstone registers network elements, selects the optimal transport elements, provisions the network, and monitors the actual characteristics for compliance of a service against a desired behavior.



The Soapstone abstraction layer can create a "virtual resource" that also maps to emerging standards for service management from Telemanagement Forum (TMF) and IPsphere. Soapstone controlled virtual resources can also be integrated with SDP-based features and applications that support IPTV, videoconferencing, SaaS, and other services. By providing a simple and technology-neutral interface for applications to use in brokering network resources, Soapstone facilitates the trend toward application-driven networking.

NTT DoCoMo Achieves 5 Gbps Packet Transmission in 4G

NTT DoCoMo released details of a fourth-generation (4G) radio access network field trial in which it achieved a maximum packet transmission rate of approximately 5 Gbps in the downlink using 100MHz frequency bandwidth. The 5 Gbps downlink was established to a mobile station moving at 10 km/h. The field experiment took place in Yokosuka, Kanagawa Prefecture on December 25, 2006.



The result doubled the previous maximum speed of 2.5Gbps, which NTT DoCoMo achieved a year earlier, by increasing the number of MIMO transmitting and receiving antennas from six to 12 each, and by using proprietary received signal processing technology.



As compared with the December 2005 test, the frequency spectrum efficiency, or the ratio of data transmission rate to channel bandwidth, was also doubled from 25bps/Hz to 50bps/Hz (5Gbps/100MHz).

Tropos Debuts Spectrum and Application Based Routing Engine for Wireless Mesh Networks

Tropos Networks introduced its Spectrum and Application Based Routing Engine (SABRE), a mesh software system that enables intelligent integration of parallel network operation across multiple frequency bands and radio types. The new capability could be used by wireless network operators to reserve spectrum and radio interfaces for specific applications or users.



For example, a municipality could carry video surveillance traffic in the 5 GHz band while using the 2.4 GHz band for consumer access. The municipality could switch the video surveillance traffic to the 2.4 GHz band when there is congestion or a failure in the 5 GHz band while disallowing consumer access to shift to the 5 GHz band under similar circumstances.



Tropos' SABRE software, which will an optional capability in the company's MetroMesh routers, provides rule-based traffic segmentation, carrying traffic for different applications on different spectrum and radios while supporting dynamic fault tolerance in the event of link congestion or failure. Parallel networks using different frequency bands and radios can be configured at the client, mesh and/or capacity injection layers. SABRE dynamically routes traffic based on application, service, priority or other configurable rules. Different frequency bands can carry traffic for different applications or users. SABRE automatically detects faulty, congested or otherwise sub-optimal links at each layer in the network and seamlessly routes traffic to the optimal band for dynamic capacity expansion and fault tolerance.



Tropos said that with its future MetroMesh routers supporting licensed band operation and new radio types such as mobile WiMAX, a similar scenario will be enabled for carriers who wish to provide premium service with a licensed band and standard service with an unlicensed band. Again, SABRE could be configure to switch licensed band traffic to the unlicensed band but not vice versa, providing fault tolerance for the premium service traffic while reserving the licensed spectrum for premium users. Also, carriers could program SABRE to use unlicensed spectrum when its use enhances overall system capacity.



Tropos said the capabilities will be available in mid-2007. http://www.tropos.com
